I've had this door bell now for a good year and i can't say how much i love it. When i first purchased it i was a little sceptical on how it would work being that it was such a bargain but I can't say enough good things about it. I change the tone every once in a while to switch things up. When the batteries die it has a backup. Is loud enough for me to hear it no matter where i am in my 2 floor hourse. This has never given me any problems and i will be purchasing another one for my rental unit. it beats running wires. Get more detail about GE 19208 Wireless Door Chime, White.
